Sony SXRD 4K manual Circuitry, Optional Input Board Description

Circuitry

To accommodate the full range of SD, HD, computer and Digital Cinema inputs, the projectors have four input slots that accept optional input boards.

Optional Input Board	Description
LKRI-001	Analog Input Board
LKRI-002	HD-SDI, SD-SDI (4:2:2) Input Board
LKRI 003	Dual-Link HD-SDI (4:4:4), Single-
	Link HD-SDI (4:2:2) Input Board
LKRI-004	DVI Interface Input Board

Internal signal transport is accomplished by Low Voltage Differential Signal (LVDS). The projectors can put a single SD, HD, computer or Digital Cinema image across the entire screen, show a quad split of four simultaneous images, or show two simultaneous images. The switching and matrixing is handled by the MX board.

Primary signal processing is handled by the four PR boards, which apply gamma, contrast, brightness, color, sharpness and color temperature adjustments. The projectors offer a gamma curve of 2.6 (recommended by DCI) as well as gamma of 2.2 and 1.8. The LPD panel driver board operates with 12 bits of precision, for extremely natural images.
